Solar Cells could be produced with Inkjet technology similar to that used in office printers; according to researchers at Oregon State University. A layer of composed copper-indium-gallium-selenium is printed onto the surface of a cell, applying a technique similar to a inkjet; but with a special type of ink.
Cells produced in this way have recorded energy-conversion efficiencies of around 5%; which is quite remarkable considering this is the level Amorphous Thin Film solar technologies produced for quite some time prior to recent efficiency increases.
Researchers aim to increase the efficiency level to around 12%, which is the point at which they consider commercially viable.
It is reported that this technique is quicker and cheaper than traditional solar cell manufacturing techniques, and could reduce raw material waste by up to 90%.
